The role of antidiuretic hormone and aldosterone in the dehydrated and rehydrated camel

1. 1. Aldosterone secretion was higher in normally watered camels in summer than in winter. 2. 2. Aldosterone and ADH secretion increased following dehydration. It is suggested that the ADH. besides its water reabsorptive functions in the kidney, initiates aldosterone secretion. The aldosterone then works primarily on the colon causing absorption of salt and water. 3. 3. When the camels were rehydrated the aldosterone and ADH secretion diminished, but to prevent hemodilution great amounts of aldosterone were secreted 24 hr following drinking.
